The proposal, made in a statement issued by the Iranian Embassy in Moscow, would offer an alternative to a Russian proposal to enrich Iran's uranium on Russian soil.
That proposal was intended to allay international fears that Iran may be seeking to produce atomic weapons.
Russia's Defense Minister Sergei Ivanov called on March 28 for Iran to say "unambiguously" whether it will accept or reject the Russian offer.
The five permanent United Nations' Security Council members, together with Germany, meet in Berlin on March 30 to discuss what next steps should be taken to resolve the crisis triggered by Iran's pursuit of a nuclear program.
China's Foreign Ministry has expressed hope for the meeting, saying there is still room for negotiation.
